"If I download a file onto a disk, I don't have to worry about a viruses." - This is not true, just because you've placed a file on a diskette or moved a file from a diskette to your hard drive does not mean that your computer cannot be infected. Many viruses are memory resident and capable of loading themselves into memory once a diskette is placed in the computer.
"If I buy sealed software I don't have to worry about viruses." or "If I just buy registered software I don't have to worry about viruses." - This is not always true, just because the program may be surrounded in plastic doesn't mean that it cannot be infected with a virus. When a software program is saved onto a diskette or disc if that computer or program is infected the virus will attach itself. Although this issue very rarely occurs it is still a possibility.
"If I don't download anything off of the Internet I don't have to worry about viruses." - This is definitely not true. Although most companies and web sites will scan the filesviruses before they make them available to download some may not. In addition many people create a site or a file to download with the intention of spreading a virus, spyware, Trojan horses, or other malware. for
"If I just read my e-mail, I will not have to worry about viruses." - Not true; there are viruses out there that are distributed through e-mail; also, files can be attached with e-mail and if executed can infect the computer. Today this is one of the most common ways computer viruses spread around the world.
"If I don't get on the Internet I don't have to worry about viruses." - This, unfortunately, is not the case. Although many viruses are spread over the Internet today it is still possible to contract a computer virus form any diskette or disc you put in the computer.
"You can contract viruses from just looking at web pages." - Not true. However, you can contract a virus if you download and execute a file from that web page. In addition spyware and other scripts can be executed from just viewing a web page. Although these programs are not designed to delete files on your computer they should be considered a privacy violation.
